On my last outing to the Gulf, on the first dive, I was enjoying very much having no students along for a change, diving with the Lovely Young Kat and our daughters. It is a special delight to see the girls finding fascinating critters and excitedly showing them to each other and to us.
Even though I had no students, out of habit I made a "final sweep" of the site before ascending, and saw two divers from our boat at about 70' heading up the anchor line of a second boat tied into the site... so, being the helpful fellow that I am, I went to them and signalled this was the wrong line, and pointed in the direction of ours, which was tied to the other end of the wreck, about 50 yards away. I also out of habit checked their gauges...
Great Zot!
While one diver was just fine, with 900 psi, the other had 263 psi and 12 minutes decompression obligation on his computer - and was totally oblivious to both. Grabbing him firmly by the arm, and handing him my long hose, I led him back to our anchor line while making a one minute stop at 40' and a gentle ascent to 15. Still not realizing what his computer was telling him, this rocket scientist signalled me it was time to ascend after 3 minutes at 15... still had 9 to go with a 10' ceiling on his computer. Had to write him a note on my slate to explain why I wouldn't let him ascend.

Now for the bad part... I happen to know this fellow was trained to know both how to plan dives, how to read what his computer was telling him, and had great emphasis placed on monitoring time, depth and gas supply during his training. I know he made 100% on his OW exam and 100% on his tables exam (the shop where he trained gives an extra tables exam). I know his in water skills are flawless, and that he has excellent buoyancy control. I know all this because he was one of my own students!
AAAaaarrrrgggghhhhhhh!
